Background technology
Long-spiral drilling machine is a kind of stake construction equipment for soil layer pore-forming operation, and it mainly utilizes long screw drill rod one-step pore-creating and the rig of Ti Zuan limit, limit perfusion。Long screw drill rod is to be saved short auger stem by 3 to 5 to assemble, bore under every time, all need to carry out Assembling when carrying brill, in current prior art, when long screw drill rod is assembled, interior six square joints and the outer six square joint bearing pins be with by short drill pipe itself between every two joint short drill pipe are attached；When dismantling each joint short drill pipe, it is necessary to be clamped by clamping brace seat, then fix drilling rod mandrel, to realize the dismounting of long screw drill rod。
At present, the device of the designed clamping brace seat clamping drilling rod mandrel produced of domestic and international each long-spiral drilling machine manufacturer is both needed to manually to be operated, when dismounting drilling rod each time, by workman, clamping brace seat is put on casing to step up, fixing drilling rod mandrel, manually remove this device again after dismounting finishing drilling bar。There is following defect in the structure of the prior art: 1, the repeated removal operation of this long screw drill rod is more, and the device of this clamping drilling rod mandrel is due to heavier mass, it is necessary to 3 to 4 people carry together, take more personnel, waste of manpower, at the bottom of efficiency of construction, construction cost is high；2, there is potential safety hazard in operation in workman。
Summary of the invention
For above-mentioned prior art Problems existing, the present invention provides a kind of long screw auger driver drilling rod automatic clamping device, when wanting dismounting drilling rod, clamping brace seat can turn to drilling rod position automatically and drilling rod mandrel is stepped up, fixes；When not needing dismounting drilling rod, it is possible to achieve automatically and quickly clamping brace seat is rotated to fixed position, do not affect normal construction operation；Improve efficiency of construction, reduce construction cost, stop potential safety hazard。
To achieve these goals; this long screw auger driver drilling rod automatic clamping device includes the short drill pipe being respectively welded outer six square joints and interior six square joints at two ends; more piece short drill pipe is fixedly connected into drilling rod assembly by pin shaft II; being nested with casing outside drilling rod assembly, casing plays the effect of protection, guide rod assembly；
Connecting oil cylinder by bearing pin I on the support of described casing, described oil cylinder is connected with one end of guider by pin shaft III, and the other end of described guider connects clamping brace seat, fixing connection arc clamping plate on described clamping brace seat。
Further, described guider is universal socket。
Further, described casing welds arc positioning baffle。
Compared with prior art, this long screw auger driver drilling rod automatic clamping device provides the benefit that:
1, adopting automatic telescopic oil cylinder, freely the stretching of oil cylinder can automatically change clamping brace seat and put, and when dismounting drilling rod, oil cylinder can ensure that clamping brace seat does quick rotation around bearing pin, and move to can the position of clamping drilling rod mandrel；
2, clamping brace seat can effectively be stepped up by clamping device, fix drilling rod mandrel, it is ensured that drilling rod dismounting quick, convenient, the cycle that minimizing manually clamps, changes, improves efficiency of construction, reduction construction cost, stops manually-operated potential safety hazard；
3, the bearing pin position between oil cylinder and clamping brace seat can be regulated by guider, it is to avoid bearing pin stress is excessive and damages。

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described。
As depicted in figs. 1 and 2; this long screw auger driver drilling rod automatic clamping device includes the short drill pipe 7 being respectively welded outer six square joints 2 and interior six square joints 5 at two ends; more piece short drill pipe 7 is fixedly connected into drilling rod assembly 3 by pin shaft II 6; being nested with casing 4 outside drilling rod assembly 3, casing 4 plays the effect of protection, guide rod assembly 3；
As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the support of described casing 4 connects oil cylinder 8 by bearing pin I 1, described oil cylinder 8 is connected with one end of guider 10 by pin shaft III 9, the other end of described guider 10 connects clamping brace seat 11, fixing connection arc clamping plate 12 on described clamping brace seat 11。Clamping brace seat 11 can be rotated around bearing pin I 9 by the guide effect of the flexible of oil cylinder 8 and guider 10。
Further, described guider 10 is universal socket, and the connection pin shaft III 9 between oil cylinder 8 and clamping brace seat 11 can be protected while clamping brace seat 11 is played rotary steering effect will not to damage because stress is excessive。
Further, described casing 4 welds arc positioning baffle 13, it is possible to block clamping bearing 11, it is simple to clamping bearing 11 action。
As shown in Figure 7, the operating process of this long screw auger driver drilling rod automatic clamping device is, when wanting dismounting drilling rod assembly 3, controlling equipment by hydraulic oil cylinder driving can make oil cylinder 8 automatically and rapidly promote clamping brace seat 11, guide effect by guider 10, clamping brace seat 11 will be around pin shaft III 9 and rotates, when rotating short drill pipe 7 place to end, casing 4 welds arc positioning baffle 13, clamping bearing 11 can be blocked, in clamping bearing 11, the fixing arc clamping plate 12 connected can block and fastens drilling rod mandrel, helical blade on drilling rod is made to be placed on clamping brace seat 11, avoid the whereabouts of drilling rod assembly 3, now dismounting connects the pin shaft II 6 between two adjacent sections short drill pipe 7, thus completing the dismounting of drilling rod assembly 3；When drilling rod assembly 3 is normally carried out drilling construction operation, clamping brace seat 11 is rotated to Fig. 3 position by automatically retracting of oil cylinder 8, does not interfere with the normal construction of long-spiral drilling machine。
Clamping brace seat, when dismounting drilling rod, can be turned to drilling rod position and drilling rod mandrel be stepped up, fixes by this long screw auger driver drilling rod automatic clamping device automatically；When not needing dismounting drilling rod, it is possible to achieve automatically and quickly clamping brace seat is rotated to fixed position, do not affect normal construction operation；Reduce the manual operation cycle, improve efficiency of construction, reduce construction cost, stop potential safety hazard。
